What Is A Good Score For The ECAA Cambridge?

If you are applying to study Economics at Cambridge, you will soon be sitting the ECAA, or Economics Admissions Assessment. But what exactly is a good ECAA score? While the test itself has changed, the skills and aptitudes that admissions tutors look for have not, so it can be very useful to look at the scores achieved by applicants in recent years.

The ECAA is no longer being used for Cambridge Economics. The TMUA is used instead for 2022 Economics Applicants. 

If you’re applying to study Economics at Cambridge, you’ll soon be sitting the ECAA, or Economics Admissions Assessment. But what exactly is a good score on the ECAA?

As one of the most competitive courses at Cambridge, with only 12.5% of applicants accepted in 2020, you’ll want to make sure that your score gives you a serious chance of receiving an offer.

The specification for the ECAA has changed over the last few years, with more time given to the essay, and the addition of five extra Advanced Maths questions. You can read more about these changes, and how best to prepare for the test in our detailed article on the ECAA.

Although the test itself has changed, the skills and aptitudes that admissions tutors are looking for have not, so looking at what scores were achieved by successful applicants in recent years can still be very useful.

what is a good score on the ECAA?

The ECAA is made up of three parts, a Problem-Solving section, an Advanced Maths section, and an Essay section.

Over the last few years, the average score for the Problem Solving section among all applicants is around 4.1, which equates to just over 12/20 in the raw marking scale. You can see the distribution of these scores below.

ECAA Section 1b scores 2020

The average score in the Advanced Maths section over the last few years is 4.0, which again using the conversion table below, equates to 8/15. These averages demonstrate just what a difficult test this is – the average applicant for Economics at Cambridge have GCSE scores of 7 A*s and 2 As, and yet they are only scoring just over 60% in the Problem Solving, and 53% on this test.

Scores in the Essay section of the exam are stronger through, with the average applicant scoring 5.3/9.

The distribution of scores is much narrower here, with much less variance in the quality of essay writing:

But what about applicants who get offers?

How different are their scores?

Looking at historical data, in 2019, there was a big gap between the average applicant and the average offer holder, with the average offer holder scoring 5.7 in the Problem-Solving section, 5.9 in the Advanced Maths section, and 6.3 in the Essay section.

To give an even clearer picture, we’ve presented these averages including students who didn’t receive an offer, to make the gap clearer.

Advanced Maths3.64.05.9

If you’re using these numbers to compare against your own performance on Past Papers, you can convert your raw scores to the scaled scores used here using the table above.

How much does the ECAA matter to my application?

We don’t know for certain how the different parts of the test are weighted by admissions tutors when making their decisions, or how big a part your test performance plays in whether or not you receive an offer. However, using the information available to us, we can make a few claims that are backed up by the evidence.


44 applicants scored 9.0 on the Problem Solving section, the highest possible score, and of these, 28 received offers. At 63.6%, compared with the 16.3% average chance of receiving an offer, this shows a big boost to your chances.


Numbers are very similar for the Advanced Maths section, with 28 of 46 students who achieved the top score receiving offers. 10 of these students scored 9.0 in both sections, so do bear in mind we’re talking about 16 applicants scoring 9.0 in both, of whom 10 received offers.


When it comes to the Essay, again things are a little tighter. Only 12 students were awarded a 9.0 on the essay, with 6 of these receiving offers. 3 of these applicants performed particularly poorly on the Problem Solving and Advanced Maths sections, scoring an average of 1.4, showing that essay writing alone won’t get you a place at Cambridge for Economics.


A further 90 applicants scored an 8.0 on the essay section, with 32 of them receiving offers. The table below sets out the relationship between Essay scores and the number of offers made for each score.

Of course, students who excel in the tests are likely to also be those who excel in the interview, so these figures are only indicative. Only one student in 2019 scored 9s in all three sections of the test, and they didn’t go on to receive an offer, so take these probabilities with a pinch of salt.


Also bear in mind that everything we’ve written about above can be accused of confusing correlation with causation. There’s nothing you can do in the test that you can’t undo in the interview and vice versa. Our goal is to give applicants the best and most complete information possible to help guide their decision making.

Where does our data come from?

Thanks to the Freedom of Information Act 2000, it’s possible to look at fairly detailed data on Cambridge Admissions Assessments, which is what we’ve used here. If you’d like to see the data for yourself, you can access it here.

The ECAA is no longer required for Cambridge Economics applicants, you need to score highly on the TMUA instead. 

The UniAdmissions TMUA Programme will rapidly boost your score and triple your chances of succeeding in your application.

Our expert tutors will guide you through past papers in mock exam scenarios so that you are well-prepared by the time your exam comes around. UniAdmissions helps students refine and hone their abilities so that they’re exam-ready on test day for all aspects of the TMUA exam.
